HEATING RAILWAY-CARS.

:SPECIPICATION forming part of Letters Patent No. 387,173, dated July 31, 1888.

Application filed December 10, 1887. Serial No. 257,556. (No model.)

To all whom it may concern.- I

Be it known that we, VILLIAM A. LYON and SYLvEsTEE L. Moons, citizens of the United Slates, residing at Danbury, in the 5 county of Fairficld and State of Connecticut, have invented new and useful Improvements in Apparatus for Heating Rnilwayflars, of which the following is a specification.

Our invention relates to an apparatus for X heating railway-ears; and it consists of con structions and combinations, all as will here iuafter be set forth in the specification and particularly pointed out in the claim, reference being had to the accompanying drawing,

I which represents a side elevation of a steamlocomotive and arailway-car provided with a heating apparatus embodying our improvements.

A is ascction of a hollow metal chamber located in the fire box and held in position by means of lugs a on the inside of the lire-box. On the under side of the chamber A, where the heat is greatest, a stratum of fire'bricl E, is placed, to protect the chamber from the heat.

B is a funnelshaped cold-blast pipe, having a sieve-cap, b, over its month, which opens at 0 into the chamber A, through which air is drawn to be heated.

C is the distributing-pipe, through which the heated air passes from the metatcliamber to the cars, and is connected with the chamber at c.

The funnel-shaped blast'pipe B and thedis- 5 tributing-pipe Gare screwedinto and through two sleeves, D D, and the sleeves are in turn screwed into and through the two shells of the outer legs of the boiler. These sleeves take the place of several stay-bolts, and the man- 40 ner in which they are screwedinto the boilerlegs strengthens the boiler. The distributing pipe 0 is coupled with the pipe leading into the cars at G. The carpipe leads to a register, 1, through which the heated air enters the car, the register being provided with a valve- 5 damper, K, which has a lever, in, to operate it, whereby the supply of hot air to the car can be regulated.

To produce a draft when the locomotive is at rest, we insert a steampipe, 1?, into the dome, and connect it at p with the distributing-pipe O. The pipe P is provided with a valve, m, to regulate the flow of steam. The steam may be turned on while the locomotive is running as well as when at rest, as it moist- 5 ens the air' and renders it better fitted for respiration.

The operation is as follows: Cold air is taken in through the blast-pipe B and passes into the metal chamber A, where it is heated, and then passes out through the distributing-pipe Oand into the car-register I, which is regulated by the damper K. I

Having fully described our, invention, what we claim as new, and desire to secure by Letters Patent, is-

The combination, in a heating apparatus, of the metal chamber A, having underneath protective fire-brick, E, and resting upon lugs a on the inside of the tire-box, the cold-blast 0 pipe B and distributing-pipe O, screwed into and through sleeves D D,said sleeves screwed into and through the shells of the outer legs of the boiler, and the steam-pipe P,leading from the dome and connecting with the distributing-pipe leading to the car, substantially as shown and described.
